Silica exposure an increased risk for lung cancer?

A newly published study of a large population of Chinese tin and pottery workers has found that exposure to airborne silica dust is associated with a significant increase in the risk of developing lung cancer. The study, printed in the American Journal of Epidemiology, measured cumulative silica exposure in a group of more than 30,000 workers over a 44-year period. These findings, which confirm that silica is a human carcinogen, are consistent with the preliminary risk assessment in OSHA's new proposed rule to protect workers from occupational exposure to crystalline silica, and have important implications for public health.

OSHA invites and strongly encourages the public to participate in the process of developing a final silica rule through written comments and participation in public hearings. You may read the notice of proposed rulemaking, by visiting https://federalregister.gov/a/2013-20997.
